Please see this link to the Law Commission’s consultation paper on reform of planning law in Wales, which is open until 1 March 2018. I would like to draw your attention to Chapter 13 (p.273-311) in particular as this relates to works affecting listed buildings and conservation areas. The paper includes a recommendation that a unified consent regime is introduced to cover planning permission, conservation area consent and listed building consent.
Although the paper only relates to Wales, it is likely that any changes introduced will have ramifications in future for the consent regimes in other parts of the UK. It is therefore important that the views of the professional bodies and other organisations with an interest in the historic environment, irrespective of which part of the UK they operate in, are properly represented.
